THEODORE C. PERRY, OF CHICAGO, ILLINOIS.

PORTABLE VENTILATOR.

SPECIFICATION forming part of Letters Patent No. 307,794, dated November 11, 1884.

(No model.)

To all whom it may concern,.-

Be it known that I, TnnoDoRn C. PERRY, a citizen of the United States, and a resident ot' the city of Chicago, in the county of Cook and State of Illinois, have invented certain Ventilators, of which the following is a specitication.

My invention. is a portable Ventilating device constructed as fully described hereinafter, and adapted to be applied to a window or other opening, so as to effect or assist in the ventilation of a room or chamber.

In the drawings, Figure I is an elevation of sufficient of a window and sash to illustrate my device and the method of its application. Fig. .2 is an edge view of the device shown in Fig. I. Fig. 3 is a section illustratinga modification.

The object of my invention is to provide al readynieans of Ventilating a room or other space in th ose cases Where ordinary appliances cannot be used in consequence of a lack of power to drive them, and this object I effect by the use ot' a strip or panel with an opening receiving or adjacent to a Ventilating-wheel, said strip being adapted for ready application to a door, window, or transom, flue-opening, or any ofthe usual inlet or outlet openings of a building, and carrying a motor device by which the fan is rapidly revolved. Thus the board or panel A is adapted to iit the frame of a window beneath or above the sash or tov one of the openings in the sash, or to a transom or door opening, &c., and carries a propelling or exhaust wheel or fan, B, the shaft c of which'turns in suitable bearings, I), so arranged as to support the wheel in or opposite an opening, d, in the panel. Upon the panel is also arranged a motor which may be a clockwork, C, or an electric inotor, C', so connected by gearing, belts, or otherwise directly or indirectly to the shaft of the wheel, that the latter is driven thereby with a rapid motion, so

as either to expel the air from the apartment or carry it into the saine. By this means an apartment may be readily ventilated by simply inserting the panel in the opening to which it is adapted and then releasing or setting in motion the driving mechanism.

In Fig. l the lower wheel, B, is represented as driven by a belt from the clock-Work C, the panel being held in place in the windowframe by the sash I, and a second wheel, B', the panel A of which tits a pane-opening, is driven from the rst.

In Fig. 3 the armature of the electromotor C is mounted direct-ly on the shaft a, and the wires -lconnected with the generator of any suitable kind at any available point.

Instead of a spring-motor or electric motor, the fan may be driven by means of compressed air or steam connecting` with a suitable en. gine mounted upon a panel, A, as shown in Fig. l in dotted lines.

I do' not claim the Ventilating-Wheel arranged in an opening to ventilate a room, this heilig old, my invention consisting in combining such a wheel and its motor with a panel by which it may be applied to the usual openings of the room, as above set forth.

I claim as my invention- 1. A Ventilating device consisting of a panel adapted to a window or other opening of a room, a ventilating-wheel mounted in bearings adjacent to an opening in said panel, and a motor device carried by the panel and connected to convey motion to the ventilatorwheel, substantially as set forth.

2. The combination of the panel, ventilatorwheel, and motor mounted directly upon the shaft of the wheel, substantially as specified.

In testimony whereofI have signed my name to this specication in the presence of two subscribing witnesses.
